Engineered to realise your vision.

Composite curtain walling with superior strength and thermal performance.

As a warm facade (thermally broken) stick system design, the REHAU Polytec 50 curtain walling system has been engineered to give you complete architectural freedom and efficient on-site assembly.

Unlike most curtain wall systems, which are mainly aluminium, Polytec 50 uses a system that has the structural capabilities of steel reinforcement, the design and finish of aluminium on the exterior, and the warmth and low maintenance benefits of PVCu on the interior.

As steel has an E-modulus three times greater than aluminium, Polytec 50's structural capabilities can easily outperform aluminium sections with the same geometry, making it perfect for larger spans. It's for this reason it's being specified in many luxury housing developments, schools, leisure facilities and commercial offices across the world. It's a highly innovative system that combines economical polymer materials with the advantages of a conventional transom/mullion construction, yet ingeniously uses the same profile as both transom and mullion - helping to eliminate wastage.

Polytec 50 also has incredibly slim and attractive sight lines, just 50mm, with different aluminium caps available in many different colours and finishes. This gives you total flexibility to achieve the exterior styling you require.

Tried and trusted worldwide, it's the cost-effective, versatile curtain walling system you're looking for.
